Is this supposed to go into the 1.3.2 release?

Directly or through Kim's 83xx custodian repo?

Kim?

Hi Wolfgang,

I don't know what version Dave intended here either; if he wants it in 1.3.2 I'll apply and ask you to pull.

Hello Wolfgang and Kim, I'm mistaking to read Kim's message,

Actually, the patch is *not* emergency, it will go to 1.3.2 release. Kim, please apply it to your tree. Sorry for that.
